TOOL FOR DETACHI'NG PUPPE'r-vALvEs FOR GRINDING, CLEANING, on OTHER rrmrosns. p

Application filed February 7, 1916.

To all whom it may concern Be it known that I, Josnr-H ENDERLIN, Jr., a citizen of the United States, and residing at Northport, Long Island, in the county of Suffolk and State of New York, have invented certain new and useful Improvements in Tools for Detaching Puppet- Valves for Grinding, Cleaning, or other Purposes, of which the following is a specification, such as will enabl those skilled in the art to which it appertains to make and use the same.

This invention relates to tools foruse in detaching the puppet valves of internal combustion and other engineS'for the purpose of grinding and cleaning or repairing saidvalves, and the object thereofis to provide an improved tool of this class.

which is simple in construction, eflicient in operation and which can be easily manipulated for the purpose specified.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure l is a side view of my improved tool indicating the method of its use; and,

Fig. 2 a side edge view of the tool detached looking in the direction of the arrow 2 of Fig. 1.

In the drawing forming part of this specification, I have indicated at at a part of the cylinder of an internal combustion or other engine and at b an ordinary puppet valve provided with a stem 0, and at d I have shown a part of the support for the operative means of the valve, part of which is shown. I have also shown at e a part of the valve operating means and on which the end of the stem 0' of the valve normally rests, and mounted on the stem 0 is a cupshaped disk 7 between which and the cylinder a is placed the usualspiral spring 9 which bears on said disk, and said disk is held in its proper position by a stop pin it passed through said stem. All this construction is old and may be ofthe usual or any preferred form.

In the construction of my improved tool I provide a yoke-shaped handle member z' through the cross head portion 2' of which is passed a screw j provided at its outer end with a thumb nut is, and pivoted between Specification of Letters Patent.

Patented Oct. 3, 1916 Serial No. 76,562.

the ends of the side portions of'the yoke- Shaped handle member 71, as shown at 71 are two levers m whichv operate between the sides of the yoke-shaped handle member 2' and the outer ends of which are provided with jaws m having forked heads m The inner endsof the levers m are curved outwardly as shown at m*, and pivotally connected therewithas shown at m are links a which are pivotally connected at a}, and the screw j is provided at its inner end with a flat head j through which the pivot pin at: n passes. l/Vith this construction the thumb nut is may be turned and moved outwardly on the screw j in order to permit thejawsm to be brought approximately together, and-when saidjaws are in this positionone of them is placed on the support cl of the means for operating the puppet valve and the other under the. disk f as shown in Fig. 1, after which the nut is turned and moved inwardly on the screw y, and this operation draws the inner ends of the levers m together and forces the jaws m apart, and this operation releases the tension of the spring g and the pin it may be removed and the valve 6 may be removed or detached for grinding, repairing and other purposes. The replacement of the valve 7) will be the reverse of that above described, the valve stem being first inserted after which the spring 9 is placed" in position and the disk f mounted on the stem 0, after which the tool is operated to raise said disk against the pressure of the spring 9 in order to permit of the insertion of the pin it, and in both of the described operations it will be understood that the stop pin it is movable through the forked head m of the upper jaw member m and it will also be observed from Fig. 2 of the drawing that the head m of the upper jaw member is wider than the head m of the lower jaw member. The aperture i in the headof the yoke-shaped handle member through which the screw 7' passes is large enough to permit said screw to swing freely within certain limits in the plane of the levers m and-this will permit of the manipulation of said screw so as to swing the inner ends m of said levers and the links a laterally so as to The method of operating my improved toolwill be readily understoodby all those familiar with puppet valves, the method of their mounting and the means employed for detaching the same for various purposes; and while I have shown and described the construction or" my improved tool which I prefer, my invention is not limited to the exact details of construction herein shown and described, and changes therein and modifications thereof may be made, within the scope of the appended claims without departing from the spirit oi my invention 'orsacrificing its advantages.

I-Iaving' fully described my invention,

' 7 what I claim as new and desire to secure by Letters Patent, is

1; A tool of the class described comprising a yoke-shaped handle member, a screw passing through the head thereof, levers pivoted between the ends of the sides or" said handle member'and provided at their outer ends with jaws having forked heads,

and links connected with the inner ends of said levers and with said screw.

7 topics of this patent may be obtained for 2. tool of the class described comprising a yoke-shaped handle member, a screw passing through the head thereof, levers pivoted between the ends of the sides of said handle member and provided at their outer ends with jaws having open heads, and links connected with 'the inner ends of said levers and with said screw.

3. A tool of the class described, comprispivoted in one end thereof and provided at their outer ends with open .jaws, and means adjustably mounted in the other end oi said handle member and in operative connection with the inner ends of said levers for operating said jaws-to open and close the same. V

In testimony that I claim the foregoing as my invention 1 have signed my name in presence of the subscribing witnesses this 4th day of February'19l6.
